Nuffield Health, the country’s largest health charity, has raised £18.6m in bond funding in five weeks.
The amount invested beat the initial target of £15m. The money will be used to support the charity’s work in general.
More than 1,300 people invested in the bond, which is the largest set up by an operational charity, Nuffield said. The average investment was about £14,000 per person.
The Nuffield Health Bond offers a 6 per cent fixed return over five years for investments of between £1,000 and £250,000.
KP Doyle, group chief financial officer for Nuffield Health, said: "We are delighted with the support shown from stakeholders in our bond.
"Going significantly beyond our £15m target shows the trust our customers and staff have in the Nuffield Health brand."
